How to: Apache virtual host ssl configuration

July 3, 2009

Just thought of quickly putting this code on how to setup Apache virtual host ssl as when I initially setuped SSL certificate, it took me a while to setup. Hope this will help some one like me to quickly configure ssl on apache.

  #SSL works on port 443
SSLEngine on   #Start SSL engine
SSLCertificateFile /etc/httpd/ssl/server.crt    #path to your SSL certificate file
SSLCertificateKeyFile /etc/httpd/ssl/server.key #path to you SSL certificate key
 
ServerName example.com  #Your server name
ServerAlias example.com   #Your server name
 
DocumentRoot /var/www/example    #path to your website root folder
 
AllowOverride All
Options All
Order deny,allow
Allow from all

Once this is setupped correctly you will be able to use your URL by adding https in the beginning.

Note: You will need mod_ssl enabled in your PHP configuration

Leave your comments below if you need further help for apache virtual host ssl configuration and I will reply.

There are many tools are available that makes web developer's life easy. But below are the tools that has really made me an efficient web developer.

Subversion also known as SVN, it is an opensource software which provides revision control of the source codes, this helps to keep track on all current and past versions on each file, with note about who edited them and what they did. If some of the changes go wrong restoring to the previous running version is just few clicks away. It can also be used in place of FTP to upload files to live server, so that everytime you make some changes to you local copy, you dont have to remember the changed files to be uploaded. Simple SVN update command would do that job for you.

4. Wordpress

wordpress

Wordpress is one of the favourite blogging and CMS (content management system) engine. It is easy to use and have lots of plugin that can suit any normal websites requirement. It is backed with very huge community supporter. If you know PHP, building bespoke plugins will not be too hard in wordpress.

5. Artisteer

As I am more of a developer than a designer, this simple tool can be more useful to people like me. All you have to do is just click few buttons and you have a decent web design ready. This website's design was also done in in artisteer in just 10 minutes. All the designs made in artisteer can be easily exported to HTML/CSS or it can also be exported as wordpress, drupal or joomla themes.
